Objective: Heat stress (HS) triggers oxidative stress and respiratory alkalosis in pigs. The objective of this experiment was to study whether a short-term supranutritional amount of dietary vitamin E (VE) can mitigate oxidative stress and respiratory alkalosis in heat-stressed pigs. Methods: A total of 24 pigs were given either a control diet (17 IU/kg VE) or a high VE (200 IU/kg VE; HiVE) diet for 14 d, then exposed to thermoneutral (TN; 20°C, 45% humidity) or HS (35°C, 35-45% humidity, 8 h daily) conditions for 7 d...

Robotic surgery (RS) is a novel treatment for rectal cancer resection (RCR); however, this technology is not widely accessible. The objective of this study is to evaluate the utilization of RS in RCR compared with open and laparoscopic techniques and to assess the quality of resection. RCR from 2010 to 2012 were identified using the National Cancer Database and placed into categories: open, laparoscopic, and robotic. A total of 23,857 patients who received open, laparoscopic, and robotic RCR were included (n = 14,735 (61...

INTRODUCTION: Multimodality treatment of patients with locally advanced rectal cancer has significantly improved local disease control, however the unaltered overall survival (OS) implicates an inability to further control micrometastases, providing rationale for intensified systemic treatment. A systematic review was conducted to evaluate the efficacy and toxicity of adding oxaliplatin to a fluoropyrimidine (intervention) compared with fluoropyrimidine alone (control) in the treatment of resectable rectal cancer...

BACKGROUND: Local excision (LE) alone is associated with worse survival compared to radical surgery (RS) for T2 rectal cancer, but LE with additional chemoradiation (CRT) may improve outcomes. The objective of this study was to compare combined CRT and LE versus RS for T2 rectal cancer. METHODS: The 2004-2014 National Cancer Database was queried for patients with T2N0M0 rectal cancer undergoing LE with neoadjuvant(NA-CRT + LE) or adjuvant(LE + Adj-CRT) CRT, or RS...

BACKGROUND: Neoadjuvant chemoradiation therapy (nCRT) for rectal cancer may lead to cure. As we currently lack reliable methods to clinically confirm the absence of disease, some patients undergo radical resection and have pathological complete response (pCR) still undergo surgery. Furthermore, it is uncertain if conventional one-level histopathological analysis is accurate enough to determine complete response. Confirming pCR is essential to determine the prognosis and to consider the patient's inclusion in trials of adjuvant therapy...

Background and Objectives: To investigate critical prognostic factors for local recurrence in patients with rectal adenocarcinoma. Methods: We enrolled 221 consecutive patients who had histologically confirmed adenocarcinoma of the rectum and underwent surgery in our hospital between January 2000 and December 2014. Total mesorectal excision was performed in all patients undergoing a sphincter-sparing procedure or abdominal perineal resection of rectal cancer. To evaluate prognostic factors for local recurrence, we performed univariate and multivariate Cox regression analyses of the local recurrence rate in all patients...

To investigate the usefulness of intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) in discriminating the pathological complete response (pCR) to neoadjuvant chemoradiotherapy (nCRT) in locally advanced rectal cancer (LARC), 42 patients underwent preoperative IVIM-DWI before (pre-nCRT) and after nCRT (post-nCRT). The values of pre-nCRT and post-nCRT IVIM-DWI parameters (ADC, D, D* and f), together with the percentage changes (∆% parametric value) induced by nCRT, were compared between the pCR (tumour regression grade [TRG] 4) and non-pCR (TRG 0, 1, 2 or 3) groups and between the GR (TRG 3 or 4) and PR (TRG 0, 1 or 2) groups based on the Dworak TRG system...

In 2008, the French Public Health Committee admitted that associating ultrasound probe protection, and related precautions, and low-level disinfection would be equivalent to the intermediate level disinfection. In 2010, the French Urology Association (AFU) updated guidelines regarding trans-rectal prostate biopsies, namely preventive measures related to cross-transmission of infections. We report an evaluation of compliance to them, driven in 2016 by AFU's infection committee. Although not recommended, almost one third of the urologists still perform biopsies under general anesthesia, and two thirds of them ask for a urine culture before biopsies...

Extra-nodal mucosa-associated lymphoid tissue (MALT) lymphoma is frequently involved with the upper gastrointestinal tract, but rarely involved with the rectum. We report a case of rectal MALT lymphoma treated by radiotherapy (RT) alone. A 74-year-old woman with lower abdominal pain was diagnosed with MALT lymphoma by endoscopic mucosal resection (EMR). She was diagnosed as stage IE (Ann Arbor) MALT lymphoma by diagnostic work-up and review of EMR specimens. Definitive RT was performed with curative intent, totaling 30 Gy in 15 fractions...

Dose escalation is now the standard of care for the treatment of prostate cancer with radiation therapy. However, the rectum tends to be the dose-limiting structure when treating prostate cancer, given its close proximity. Early and late toxicities can occur when the rectum receives large doses of radiation therapy. New technologies allow for prevention of these toxicities. In this review, we examine the evidence that supports various dose constraints employed to prevent these rectal injuries from occurring...

A 27-year-old man of Eritrean origin presented with persistent left-sided abdominal pain. Initial investigation showed signs of liver fibrosis, portal hypertension and splenomegaly. A diagnosis of hepatosplenic schistosomiasis was suspected on grounds of elevated total IgE, grey area antischistosomiasis antibodies and the high endemic status of his native country. However, repeated microscopy of faecal and urine samples, as well as rectal biopsies, failed to demonstrate schistosomal eggs. Finally, the diagnosis of hepatosplenic schistosomiasis was established through demonstration of a Schistosoma mansoni egg in a liver biopsy taken in an attempt to clarify the cause of the above findings...

BACKGROUND: Colorectal cancers are the third most common cancers in women and men in the USA. While dietary and lifestyle factors such as Western diet, physical inactivity and obesity have been linked to an increased risk of this malignancy, the mechanisms for these associations are unclear. GI hormones, including ghrelin, are involved in energy balance by mediating appetite and metabolism; however, the association between ghrelin and colorectal cancer has not been studied. METHODS: We conducted a case-control study nested within the all-male Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study of Finnish smokers (aged 50-69 years) to examine serum ghrelin concentration and colorectal cancer risk...
